Working principle: before use, each feed cylinder 3 is used for storing a raw material, when the raw material is not placed, the first weight sensor 16 is used for detecting the weight of the whole feed cylinder 3, the second weight sensor 18 is used for detecting the weight of the bin box 17, the display values of the first weight sensor 16 and the second weight sensor 18 are dehaired, then the raw material with the corresponding weight is placed in each bin box 17, the second weight sensor 18 at the corresponding position is used for detecting the real-time weight, the first servo motor 20 can drive the stop plate 21 to rotate, so that the material gap 23 and the material outlet 22 are overlapped, the raw material falls out of the bin box 17, and conversely, the raw material cannot fall out;
in addition, when the electric telescopic cylinder 25 is started, the conical plug 24 is moved downwards, so that the raw material positioned on the upper side of the material dividing plate 19 falls out and enters the material mixing cylinder 4 along the material conveying pipe 8;
in the weighing process, the following modes are included:
1): the raw materials in each feed division cylinder 3 are put in the raw materials of the adaptation amount according to the proportion, taking one feed division cylinder 3 as an example, the amount of the raw materials needed to be put in is A, then the materials put in by the bin box 17 are A in theory, however, in the scheme, the materials put in by the granary box 17 are nearly 1/2A, but the real-time weight change of the bin box 17 is detected by the second weight sensor 18, that is, the weight of the bin box 17 is B in the initial state, then the weight of the bin box 17 is changed to B-1/2A after 1/2A is put in;
2): when the raw material falling onto the distributing plate 19 is not discharged, the weight change detected by the first weight sensor 16 is also B parts, then after the conical plug 24 is opened, the raw material on the distributing plate 19 enters the mixing cylinder 4, and at the moment, after the distributing plate 19 is blocked by the conical plug 24, another 1/2 part of raw material is put in again by the bin box 17, and the materials are circularly put in the mode;
In combination with the above, the weight value of the material stored on the material separating plate 19 is equal to the weight value displayed on the first weight sensor 16 minus the weight value displayed on the second weight sensor 18, wherein the material separating plate 19 is used as a second discharging structure and also as a transferring structure;
Then the following two parts occur:
X1: the actual amount of the raw material discharged from the distributing cylinder 3 in the corresponding position is smaller than the preset discharge amount, which can be understood as "error" of the weight of the raw material put in by the bin box 17, but 1/2A parts of the raw material is discharged in each cycle of the bin box 17 and the 1/2A parts of the raw material is temporarily stored on the distributing plate 19, so that at this time, the raw material on the distributing plate 19 is discharged first and the other 1/2A parts of the raw material discharged from the bin box 17 is accepted again, and the discharge is continued, but in the last step, the raw material is not discharged from the distributing plate 19, and the missing amount of the process is put in again by the bin box 17;
X2: when the actual usage amount of the material distributing cylinder 3 in the corresponding position is larger than the preset discharge amount, wherein the first raw material throwing is performed along the material conveying pipe 8, 1/2A of the raw material in another period is thrown into the material distributing cylinder according to the normal state by the material bin box 17, but in the discharging process, the electric telescopic cylinder 25 drives the conical plug 24 to reciprocate up and down, so that the raw material on the material distributing plate 19 is intermittently discharged, and the condition that the weight change of the whole material distributing cylinder 3 is detected by the external first weight sensor 16 is needed again, so that the thrown raw material is A part is ensured, that is, the raw material still remains in the material distributing plate 19, the weight value displayed on the first weight sensor 16 minus the weight value displayed on the second weight sensor 18 is the weight of the remaining raw material, and the weight value can be set as Y here, and when the raw material is thrown into the material bin box 17 next time, the thrown weight shall be: 1/A-Y;
The process is circularly carried out according to the process, and the two processes of supplementing or limiting can be carried out on the weighing process.
Example two
Referring to fig. 1 and 3, a plurality of exhaust ports 9 are formed in the upper end position of a mixing barrel 4, an outer heating sleeve 5 is arranged in the outer wall position of the mixing barrel 4, an inner sleeve 10 which is vertically distributed is arranged in the center point position of the mixing barrel 4, an electric heating rod 11 is inserted in the inner sleeve 10, a mixing plate 13 is arranged on the inner sleeve 10, the setting position of the mixing plate 13 is lower than the tail end position of a conveying pipe 8, the diameter of the mixing plate 13 is smaller than the inner diameter of the mixing barrel 4, the cross section of the mixing plate 13 is conical, and a plurality of material dividing grooves 14 are formed in the upper surface of the mixing plate 13;
The inner sleeve 10 is arranged at the upper side of the outer part of the mixing barrel 4 and is provided with a connecting driving disc 30, the inner sleeve 10 is rotationally connected with the mixing barrel 4, the outer part of the mixing barrel 4 is provided with a driving motor 12, and the output end of the driving motor 12 is connected with the connecting driving disc 30.
Working principle: after the raw materials are put into the mixing cylinder 4, the raw materials are melted into semi-fluid under the heating action of the external heating sleeve 5 and the electric heating rod 11, and when the shutoff valve 6 is opened, the melted mixture can be discharged along the rubber extrusion pipe 7;
What needs to be explained here is: the raw materials in each material distributing cylinder 3 can enter the material mixing cylinder 4 at the same time, and in the process, under the action of the driving motor 12, the inner sleeve 10 is driven to rotate firstly, and when the inner sleeve 10 rotates, the material mixing plate 13 is driven to rotate;
When the mixing plate 13 rotates, the raw materials are scattered by each material distributing groove 14 on the mixing plate, so that different raw materials are fully diffused and slowly fall into the lower side of the mixing cylinder 4 to be subjected to melting treatment, and the process ensures that the raw materials can be fully mixed.
Example III
Raw materials discharged from each material distributing cylinder 3 enter the material mixing cylinder 4 along the material conveying pipe 8, and the melting process is carried out in the material mixing cylinder 4, so that generated high-temperature gas can enter the material distributing cylinder 3 along the material conveying pipe 8, and the actual weighing effect can be influenced.
Referring to fig. 1, fig. 2, fig. 8 and fig. 9, a protective sleeve 15 is installed on the outer curved surface of each conveying pipe 8, a second servo motor 27 is installed at the inner position of the protective sleeve 15, a material distributing butterfly sheet 28 is rotatably installed at the inner position of the conveying pipe 8 corresponding to the second servo motor 27, an output shaft of the second servo motor 27 penetrates through the conveying pipe 8 and is connected with the material distributing butterfly sheet 28, arc-shaped rubber plugs 29 are installed on the outer walls of two sides of the material distributing butterfly sheet 28, the arc-shaped rubber plugs 29 and the material distributing butterfly sheet 28 are matched with the inner wall of the conveying pipe 8, and the arc-shaped rubber plugs 29 are arranged in a staggered mode along the material distributing butterfly sheet 28.
Working principle: in the initial state, the material distributing butterfly piece 28 is positioned at the inner position of the material conveying pipe 8 under the action of the second servo motor 27, and the positions at two sides of the material distributing butterfly piece 28 are completely blocked, so that the interior of the material conveying pipe 8 is not circulated;
when the material distributing cylinder 3 discharges a part of raw materials, the raw materials firstly enter the material conveying pipe 8, at the moment, the second servo motor 27 is started to drive the material distributing butterfly 28 to continuously rotate, in the rotating process, the arc-shaped rubber plug 29 on the material distributing butterfly 28 is always in contact with the inner wall of the material conveying pipe 8, in this state, high-temperature gas generated in the melting process still cannot enter the material distributing cylinder 8, but when the material distributing butterfly 28 drives the arc-shaped rubber plug 29 to rotate, the arc-shaped rubber plug 29 can grab a part of raw materials to enter the other side, namely, one side close to the material mixing cylinder 4, so that the normal input of the raw materials is ensured, and waste gas generated in the melting process cannot enter the material distributing cylinder 3.
To sum up: the discharging process is divided into a first-stage discharging mode and a second-stage discharging mode, so that the effect of successive discharging is achieved, and then the discharging process is error at a certain end, and the feeding or limiting can be carried out through the first-stage discharging mode or the second-stage discharging mode; and when different raw materials enter the mixing cylinder in the mixing process, firstly, the mixing plate is driven by the inner sleeve to rotate, so that the different raw materials can be disturbed and diffused under the action of the mixing plate, and the different raw materials are fully mixed.
